Problem deploying app to shinyapps.io due to colorspace 1.4-2

shiny shinyapps.io
1

My app works fine on Windows 10 desktop. Why I try to push it to shinyapps.io I get this error, seems to be caused by colorspace 1.4-2 not being available. I don't load colorspace but I guess it's a dependency of one of my packages (listed below)? How do I workaround this? Thanks!

Packages my app uses:

Solved. I had to install an older version of colorspace, that was on CRAN:

require(devtools)
install_version("colorspace", version = "1.4.1", repos = "http://cran.us.r-project.org")

I have the same problem with 'rpanel', tried both the latest version (1.1-4) and the older ones available on CRAN (https://cran.r-project.org/src/contrib/Archive/rpanel/), but it didn't work. Is there a way to know which package versions are available for shinyapps.io enviroment?

There's also an option to turn off package caching on shinyapps.io that might help. Choose the app then go to Application|Settings|Advanced, it's at the bottom.

If you download your app Bundle from shinyapps.io to your PC it will tell include the package list. Choose the app then Overview|Bundle [Download]. It saved as a tar file for me. Using 7zip I could open it, you will see the app files and manifest.json, which is a text file that lists also the package information.

Tried disabling cache, and even deploying the app from scratch, all to no avail.

I do not load rpanel explicitly, I guess it is required by some of the other packages, I will see if I can live without it, but other than that, I haven't a clue as to what more to try...
